P and Q are two points on latitude 55°N and their longitude are 33°W and 20°E respectively. calculate the distance P and Q measured along a the parallel of latitude
b a great circle(π=22/7, R = 6,400km) ​

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

$649.60
